Four numbers to look at before you hire your first employee

The salary is the number everyone focuses on, and it is the one least likely to be the reason the hire does or does not work.

Hiring the first employee is the point where a lot of owner operated businesses stop being able to run on instinct. Up to that moment, most financial decisions are reversible within a month. A hire is not: there is a person with a life arranged around the job, and unwinding it is expensive in every sense.

Here are four numbers worth having in front of you before that decision, and what each one is actually telling you.

1. What the hire costs, fully loaded

Not the salary. The salary plus the employer side of payroll taxes, plus whatever insurance you are required or choose to carry, plus equipment and software seats, plus the share of your own time that goes into hiring, onboarding, and managing someone for the first time.

That last one gets left out of every spreadsheet and it is rarely small. For the first few months, a new hire usually consumes more of the owner’s attention than they free up. That is normal and temporary, but it is real, and if the plan assumes the owner gets time back in month one, the plan is wrong.

2. How many months you could carry it if nothing else changed

Take the cash you actually have available, subtract what is already committed, and divide by the fully loaded monthly cost. That gives you the number of months you could pay this person out of existing cash if revenue stayed exactly flat.

This is the number that tells you whether you are making a hire or a bet. There is nothing wrong with a bet, but it should be a bet you have decided to make, with a horizon you chose in advance, rather than one you discover four months in.

A useful exercise: write down now what you would do if, six months from now, the hire has not paid for itself. Deciding that while you are calm produces a very different answer than deciding it while you are worried.

3. Your gross margin

Revenue minus the direct cost of delivering it, as a percentage. This number converts the hire from an expense into a target.

If the fully loaded cost is five thousand a month and your gross margin is 60 percent, the hire needs to be associated with roughly eight thousand three hundred a month in additional revenue to break even, not five. If your margin is 30 percent, the same hire needs around sixteen thousand seven hundred. Same person, same salary, completely different decision.

This is also why the answer to "can I afford to hire" is so rarely a general one. Two businesses with identical revenue and identical bank balances can be in opposite positions.

4. How predictable your revenue is, not how large

Most owners know their average month. Far fewer know their worst month in the last two years, or how often a month comes in more than 20 percent below the average.

Payroll is a fixed obligation landing on a fixed date. Revenue that averages out fine across a year can still fail to line up with payroll in a specific month, and averages hide exactly that. A business with lumpy revenue and a long client payment cycle needs more cushion than the average suggests, and a business with recurring contracted revenue needs less.

If you have never looked at your revenue month by month across a couple of years, that is usually the single most informative hour you can spend before making this decision.

What these numbers will not tell you

They will not tell you whether to hire. They rule out some decisions and make the cost of others explicit, which is a different and more useful thing.

They also will not tell you whether an employee is the right structure at all. Contract help, a part time arrangement, or subcontracting a whole function are all legitimate answers, and the correct classification of a worker is a legal question with real consequences that varies by state. That one is worth asking someone about specifically rather than deciding by analogy to what another business did.

What the four numbers do is move the decision from "does this feel affordable" to "here is what has to be true for this to work." Owners who have that in writing tend to make the call faster and worry about it less afterward, whichever way they go.

If any of this sounds like your situation, a conversation costs nothing and usually clarifies what the actual problem is.
